2014 4WD GM 1500 7” KIT

Thank you for choosing Rough Country for your suspension needs.

Rough Country recommends a certified technician install this system. In addition to these instructions, professional knowl­edge of disassemble/reassembly procedures as well as post installation checks must be known. Attempts to install this sys­tem without this knowledge and expertise may jeopardize the integrity and/or operating safety of the vehicle.

Please read instructions before beginning installation. Check the kit hardware against the parts list on the rear cover of
these instructions. Be sure you have all needed parts and know where they go. Also please review tools needed list and
make sure you have needed tools.

As a general rule, the taller a vehicle is, the easier it will roll. Seat belts and shoulder harnesses should be worn at all times.
Avoid situations where a side rollover may occur. Generally, braking performance and capability are decreased when larger/
heavier tires and wheels are used. Take this into consideration while driving. Do not add, alter, or fabricate any factory or
after-market parts to increase vehicle height over the intended height of the Rough Country product purchased. Mixing com­ponent brands is not recommended.

Rough Country makes no claims regarding lifting devices and excludes any and all implied claims. We will not be responsi­ble for any product that is altered.
tion, and correct use of our products.

**Note** The electric power steering must be unplugged before any of the steering components are removed. Failure to do
so may cause damage to the electric power steering.

This kit is packaged as a leveling kit—raising the front 7” and the back 5.25”. If you desire a different look or if the vehicle
has a tool box or added weight in the rear, please consult with your sales representative about other block and u-bolt op­tions.

This suspension system was developed using a 35” x 12.5” tire with 20” x 9” wheel and a offset of –12mm to +18mm.
*Note* if wider tires are used, offset wheels will be required and trimming may be required.
NOTICE TO DEALER AND VEHICLE OWNER

Any vehicle equipped with any Rough Country product should have a “Warning to Driver” decal installed on the inside of the
windshield or on the vehicle’s dash. The decal should act as a constant reminder for whoever is operating the vehicle.
